[Glass] I bought this filter (95mm) to shoot the August 2017 eclipse. It worked perfectly. This filter, when shot in AWB (let camera choose white balance) does not add any color cast to the image. The images will be white, with no noticeable orange cast. you can always add an orange cast in post processing if desired.

I was very happy with my images in 2017 and plan to use this filter again for the upcoming April 2024 eclipse.

[Multi Coated] I bought this filter for the express purpose of a trip to the Gulf to get long exposure shots in the afternoon sun. It was amazingly good!

[Glass] Yes these cost a bit more than other brands but you do get what you pay for. You don't get the color shifts that come with Tiffens, and to some degree Schneiders. The DPs and DITs I work with still are requesting these on every shoot so it was time for me to buy a set of my own. Super happy with them.

[1.34 lb] Hi,


Purchased in late 2020 for Sigma 105mm 1.4 (Nikon).


This ND filter is really good because it does not create any color cast. The ND allows me to use the lens at f1.4 without overexposing the shadows (while using my strobes). It is a great ND filter, more neutral than a few others I purchased for a 85mm 1.8.


High recommendations.

[1.34 lb] The quality of these filters is outstanding. While they are somewhat expensive, they are worth the price point. The one thing I fail to understand is with the attention to quality and detail the weak link is the installation of the light leak gasket that is included with the filter. It is a challenge to affix it to the filter and have had difficulty with every filter I have from them. I don't know why Formatt-Hitech does not place it on the filter as part of the manufacturing process.

[8.1 x 6 x 1.7"] I had ordered a Tiffen kit and returned it, and am so thankful I did. These are seriously top notch with almost 0 color shift and NO IR Pollution!

100% worth it!

[Multi Coated] Great for long exposures, have the 6 stop and split Nd filters also from formatt Hitech, Highly recommend.

[Solid ND] For this review of my ND 3.0 filter, 10 stop, I used a tripod, the Nikon MC- 36A remote and the ND Expert Pro app. This was my very first imaging with this filter. What I was looking to see the effect of the filter and what, if any was there a shift in color. As you can see, the color shift was minor. This is a pricey filter, however, it performed as expected.

[8.1 x 6 x 1.7"] I was really pleased with the images that I have been able to create with this filter. As soon as I got it I took it to the coast and tried a bunch of long exposure shots at sunset. When I got the images onto my PC I was very happy to see that I could not tell which images I had used the filter on by looking at the colors. The colors were identical with and without the filter!

[Multi Coated] Highly recommended.


I purchased a 4-stop ND filter (1.2). It never comes off my Sigma 105mm f/1.4.


Practically all my headshots and portraits (250 clients) since the purchase were taken with this filter. I can keep the shutter speed in a reasonable range with strobes (1/30 -- 1/200) without relying on high-speed sync. I can also keep the strobes at a reasonable range (1/4 -- 1/128), which wouldn't be possible without a 4-stop loss of light transmission.


Other ND filters have funky colors - maybe I was lucky but this one has not created any noticeable color shift. Thank you Formatt!!
